Clean Up Script On Ubuntu

Many applications in Ubuntu such as clean up one of his BleachBit. We can make your own clean-up script, if you want to try it, will you follow this step by step manner.
Open your text editor application, I use gedit and then copy the script below and paste it in your text editor, then save with clean.sh name and file type .sh, put the directory in the directory / home / user

#!/bin/bash
#
# currently this simple maintenance script performs the following functions:
#   > apt-get clean
#   > apt-get autoclean
#   > apt-get autoremove
#   > apt-get purge
#   > delete orphaned packages
#   > delete residual config files
#   > delete thumbnails (current user)
#   > delete thumbnails (root)
#   > delete mozilla cache (current user)
#   > delete mozilla cache (root)
#   > delete trash (current user)
#   > delete trash (root)
#
# requires the following packages in addition to those provided by a default Ubuntu installation:
#   > deborphan (for identifying orphaned packages) - to install, type: sudo apt-get install deborphan
#   > wajig (for purging residual config files) - to install, type: sudo apt-get install wajig
#
# NOTES:
#
# 1) This script assumes that certain files/folders are in their default Ubuntu locations. If you are
#    getting 'No such file or directory' errors then look through the script below to see if your
#    files/folders are located where the script is expecting them and edit as necessary.
# 2) The goal of this script was to do a system cleanup as quickly and efficiently as possible. Some
#    functions do require confirmation but some run without user input. Because of this and the fact
#    that this script's primary purpose is to delete data from your hard drive, it should be used with
#    caution. THE ACTIONS OF THIS SCRIPT CAN NOT BE UNDONE. If you do not understand all of the
#    functions listed above, it is suggested that you gain a passing knowledge of each. The Ubuntu man
#    pages, Google search, and openubuntu.com will provide more than enough information.
# 3) The reason for deleting some files in /root may not be obvious. Picture this scenario. You open a
#    nautilus session as administrator where you send some image files to the trash and look something
#    up on the internet. Now you have created thumbnail files and mozilla cache files saved under /root
#    and the files that you trashed are sitting in /root/.local/share/Trash/files/. All of these files
#    are easily forgotten and require root access to delete when doing a manual cleanup.
# 4) This script requires a one-time setup which is as easy editing three lines listed immediately
#    below to provide information to enable the script to find your files/folders. After editing and
#    saving the file make sure that the file is executable by setting the permissions in nautilus or
#    by typing: sudo chmod +x /path/to/file/cleanup.sh

# CONFIGURATION:
#
#   change "tgeer" in the following line to reflect your username (leave the double-quotes intact):
username="tgeer"
#
# change xxxxxxxx in the following line to your mozilla profile name. You can find this information by
#   looking in /home/username/.mozilla/firefox for a folder with a name in the format xxxxxxxx.default
#   where xxxxxxxx is an eight character random alphanumeric string. The eight character string is your
#   mozilla profile name. ie. if the folder is named te3n7ssp.default then your profile name is: te3n7ssp.
userprofile="vkuuxfit"
#
#   change yyyyyyyy in the following line to root's mozilla profile name. Use the same method as above to
#   find it but look in /root/.mozilla/firefox instead.
rootprofile="etjkoe2b"

#
homepath="/home/"$username"/"
